- Seals: Stop brake fluid from leaking out of the caliper.
- Slide pins: Permit the caliper to maneuver on its mounting bracket.
- Bleeder screw: Used to take away air from the caliper throughout brake fluid bleeding.
The brake caliper operates as follows:
- When the brake pedal is depressed, hydraulic stress is generated within the braking system. This stress is transmitted to the brake calipers.
- The hydraulic stress pushes the pistons contained in the caliper, inflicting them to increase. The pistons, in flip, push the brake pads in opposition to the brake rotors.
- The friction between the brake pads and rotors slows down or stops the automobile’s wheels.
- When the brake pedal is launched, the hydraulic stress drops, and the pistons retract.
Brake calipers play an important position in guaranteeing optimum braking efficiency and automobile security. They have to be correctly maintained and inspected often to forestall any potential brake malfunctions.
